Common questions

Where does this data come from?

Your summary is generated based on Google’s Chrome User Experience Report (CrUX)—a public dataset of real user experiences for millions of websites. CrUX collects data only for Chrome browser users who opted in (excluding devices with the iOS operating system). The set is updated daily and aggregates the previous 28 days of data.

How do I read this report?

The Overview section shows if your page or site passes the Core Web Vitals. The 75th percentile means that 75% of recordings were lower than showcased Web Vitals values (e.g. 75% of page or site visitors had Largest Contentful Paint of 2.5s or less).

The overall values are categorised as good, to improve or poor. Below, with a breakdown of each metric performance, you can see the percentage of good and poor user experiences and determine where you should make improvements.

Why there is no data for my site?

Your site has to have enough traffic to be included in the CrUX report. New sites are added to the dataset every day, so keep checking in the future or try running a report on the entire domain. In the meantime, you can also monitor Core Web Vitals in Calibre!

How do Core Web Vitals impact SEO?

Google evaluates pages based on content, relevance, quality, engagement metrics and many other factors. Core Web Vitals are a page ranking signal for your pages. To give your site the best chance of ranking above your competitors, you should ensure that your Core Web Vitals fall within the recommended thresholds.

How can I improve Core Web Vitals?

There are numerous ways to improve Core Web Vitals. The best way is to continuously monitor site speed (with tools like Calibre) and follow actionable advice tailored to your context. If you don’t know where to start, read our Getting Started with Web Performance and The New Generation of Performance Metrics for Better User Experience guides!

Why does the assessment pass without First Input Delay?

First Input Delay is an optional metric in Core Web Vitals assessment. Lack of First Input Delay measurement means there is no user input for a given page visit. Without FID, your review is calculated based on the remaining Core Web Vitals: Largest Contentful Paint and Cumulative Layout Shift.

Why is First Contentful Paint listed?

While First Contentful Paint is not a Core Web Vital, CrUX returns it as a diagnostic Web Vital metric. Time to First Byte (TTFB) is another useful Web Vital that might be added to CrUX in the future.
